Powertrain Control Module Programming and Setup

POWERTRAIN CONTROL MODULE PROGRAMMING AND SETUP

The following service procedures require either a programming or a setup event be performed for a complete repair.

Powertrain Control Module (PCM) Replacement
If the powertrain control module (PCM) is replaced, the following procedures must be performed:
1. The PCM reprogramming-Refer to Service Programming System (SPS).
2. The Crankshaft Position (CKP) Variation Learn-Refer to CKP System Variation Learn Procedure in Computers and Control Systems - 4.2L (LL8).

PCM Reprogramming
- If the PCM needs to be reprogrammed, refer to Service Programming System (SPS) .
- Engine Oil Life Remaining-When available, use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before the module was reprogrammed.
- Transmission Fluid Life Remaining-When available, use a scan tool to reset the Transmission Fluid Life Remaining back to the original percentage recorded before the module was reprogrammed.

Setup for Component Replacement
The replacement of some components will require a setup procedure for complete repair.

If any of the following components are replaced, a crankshaft position (CKP) variation learn procedure must be performed. Refer to CKP System Variation Learn Procedure in Computers and Control Systems - 4.2L (LL8).
- Engine replacement
- Any engine repair that disturbs the crankshaft position CKP sensor or its relationship with the crankshaft reluctor wheel
- CKP sensor
